TE Connectivity 826953-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 826953-2 is a rectangular connector header manufactured under the AMPMODU Mod II series. This through-hole, right-angle connector features 4 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing and is designed for board-to-board or cable applications. The connector utilizes male pin contacts with tin plating on copper alloy material and PBT insulation. With an active product status and 748 units in current inventory, this component remains in production. Equivalent and substitute parts are identified to address supply chain requirements, design flexibility, or specific application constraints where alternative contact materials, insulation heights, or operating temperature ranges may be beneficial.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 826953-2 is determined by strict alignment with the following core parameters: connector type (header), contact type (male pin), number of positions (4), number of rows (2), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting type (through hole, right angle), termination method (solder), fastening type (push-pull), contact shape (square), and style (board-to-board or cable). All identified substitute parts meet these mandatory criteria.

Secondary parameters that may vary between the main part and substitutes include contact material composition, contact finish type and thickness, insulation material selection, insulation height, contact length specifications, operating temperature range, and compliance certifications. These variations are documented in the parameter comparison table to enable informed selection based on specific application requirements.

The three substitute parts identified—HTSW-102-09-G-D-RA, TSW-102-08-F-D-RA, and TSW-102-22-G-D-RA—are all manufactured by Samtec Inc. and share the core electrical and mechanical compatibility parameters with the original TE Connectivity part.

Parameter Comparison

Engineering Selection Recommendations

All four parts—the primary TE Connectivity 826953-2 and the three Samtec substitutes—maintain active product status and comply with UL94 V-0 flammability requirements. Selection between these parts is based on specific application constraints and compliance requirements.

TE Connectivity 826953-2 is suitable for applications requiring the original AMPMODU Mod II series specification, tin-plated copper alloy contacts, and an operating temperature range of -65°C to 105°C. This part carries RoHS Compliant certification and MSL 1 rating.

Samtec HTSW-102-09-G-D-RA offers an extended operating temperature range (-55°C to 125°C), gold-plated phosphor bronze contacts, and LCP insulation material. This part carries ROHS3 Compliant certification and is not subject to MSL requirements. The increased insulation height (0.240" versus 0.219") and longer post contact length (0.290" versus 0.126") must be evaluated for PCB layout compatibility.

Samtec TSW-102-08-F-D-RA provides an extended operating temperature range (-55°C to 125°C), gold-plated mating contacts with tin-plated posts, and phosphor bronze contact material. This part carries ROHS3 Compliant certification and MSL 1 rating. The shorter post contact length (0.090") requires verification against PCB hole depth specifications.

Samtec TSW-102-22-G-D-RA offers an extended operating temperature range (-55°C to 125°C), gold-plated phosphor bronze contacts, and PBT insulation. This part carries ROHS3 Compliant certification and MSL 1 rating. With the highest inventory availability (6364 units), this part provides supply chain flexibility. The post contact length (0.190") falls between the original part and other substitutes.

Frequently Asked Questions (FAQ)

Q: What are the core compatibility parameters that define substitution eligibility?

A: The following parameters must remain constant for substitution: connector type (header), contact type (male pin), number of positions (4), number of rows (2), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting type (through hole, right angle), termination method (solder), fastening type (push-pull), contact shape (square), and style (board-to-board or cable). All identified substitutes meet these requirements.

Q: How do contact material and finish differences affect substitution?

A: The original TE Connectivity 826953-2 uses tin-plated copper alloy contacts. Samtec substitutes use phosphor bronze with either tin or gold plating. Gold plating provides enhanced corrosion resistance and lower contact resistance, while tin plating offers cost efficiency. Contact material and finish selection depends on application environment, signal integrity requirements, and cost constraints. These differences do not prevent functional substitution but may affect long-term reliability in specific environments.

Q: What is the significance of contact length variations?

A: Contact length specifications directly impact PCB hole depth requirements and mating depth. The original part has a post contact length of 0.126" (3.20mm). Substitutes range from 0.090" to 0.290". Shorter post lengths (TSW-102-08-F-D-RA at 0.090") require shallower PCB holes, while longer post lengths (HTSW-102-09-G-D-RA at 0.290") require deeper holes. PCB design must accommodate the selected part's contact length specifications.

Q: How do operating temperature ranges affect part selection?

A: The original TE Connectivity 826953-2 operates from -65°C to 105°C. All Samtec substitutes extend the upper temperature limit to 125°C while raising the lower limit to -55°C. Applications requiring operation below -55°C must use the original TE Connectivity part. Applications requiring operation above 105°C must use a Samtec substitute.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: RoHS Compliant indicates compliance with the original Restriction of Hazardous Substances directive. ROHS3 Compliant indicates compliance with the updated RoHS 3 directive (2015/863/EU), which includes additional restricted substances. Both certifications indicate hazardous substance restrictions; ROHS3 represents the current regulatory standard. Applications subject to current EU regulations should specify ROHS3 Compliant parts.

Q: What does Moisture Sensitivity Level (MSL) 1 mean?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. The HTSW-102-09-G-D-RA is listed as "Not Applicable" for MSL, indicating it does not require moisture sensitivity classification. Both conditions are acceptable for standard industrial applications without special environmental controls.

Q: How does insulation material selection impact performance?

A: The original part uses PBT (Polybutylene Terephthalate) insulation. The HTSW-102-09-G-D-RA uses LCP (Liquid Crystal Polymer) insulation, which offers superior thermal stability and dimensional consistency at elevated temperatures. PBT provides cost efficiency and adequate performance for standard applications. LCP is preferred for high-temperature or high-precision applications. Both materials meet UL94 V-0 flammability requirements.

Q: Can these parts be used interchangeably on existing PCBs?

A: Functional interchangeability depends on PCB design specifications. The mating pitch, row spacing, mounting type, and contact shape are identical across all parts, enabling mechanical mating. However, variations in insulation height (0.219" to 0.240"), post contact length (0.090" to 0.290"), and contact length (0.230" to 0.264") must be evaluated against PCB hole depth, trace routing, and component clearance specifications. PCB design review is required before substitution.

Q: Which substitute part offers the best supply chain availability?

A: The Samtec TSW-102-22-G-D-RA offers the highest inventory availability at 6364 units, compared to 748 units for the original TE Connectivity part and 720-1072 units for other Samtec substitutes. This part provides supply chain flexibility for high-volume production requirements.
