TSW-103-24-TM-S Equivalent & Substitute Parts

Part Overview

The TSW-103-24-TM-S is an active Samtec Inc. rectangular connector header designed for through-hole mounting applications. This unshrouded, 3-position connector operates across -55°C to 105°C and features tin-plated phosphor bronze contacts with 0.100" (2.54mm) pitch spacing. The component is RoHS3 compliant with UL94 V-0 flammability rating and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

The 929834-01-03-RK (3M) qualifies as a substitute based on the following critical parameters:

• Connector Type & Contact Configuration: Both are unshrouded headers with male pin contacts in 3-position configuration
• Pitch Spacing: Identical 0.100" (2.54mm) mating pitch ensures mechanical and electrical compatibility
• Mounting & Termination: Both utilize through-hole solder termination with push-pull fastening
• Contact Geometry: Square contact shape in both parts ensures consistent mating interface
• Electrical & Environmental Compliance: Both feature tin-plated contacts, UL94 V-0 flammability rating, and RoHS compliance
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)
• Operating Temperature: Both support -40°C to 105°C minimum range (substitute covers the main part's full -55°C to 105°C range within the lower bound)

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-103-24-TM-S and 929834-01-03-RK maintain active product status and meet identical regulatory compliance requirements (RoHS, UL94 V-0, EAR99 classification). The substitute part is suitable for applications where the primary part is unavailable. The 3M 929834-01-03-RK features a breakaway header design and is available in higher inventory (6150 pcs vs. 1131 pcs). Contact length variations (mating and post) are minor and fall within standard tolerance ranges for 0.100" pitch connectors. The insulation material difference (PBT vs. PCT) does not affect functional compatibility, as both materials meet the same flammability and environmental specifications. Selection between these parts should be based on availability, lead time, and specific PCB layout requirements related to contact length dimensions.

Frequently Asked Questions (FAQ)

Q: Can the 929834-01-03-RK directly replace the TSW-103-24-TM-S in existing designs?

A: Yes, for applications operating within -40°C to 105°C. The substitute maintains identical pitch spacing (0.100"), contact configuration (3-position male pin header), mounting method (through-hole solder), and electrical characteristics. Minor contact length differences (approximately 0.030" shorter mating contact) are within standard connector tolerances and do not affect mating interface compatibility.

Q: What are the key differences between these two parts?

A: The primary differences are contact material (phosphor bronze vs. copper alloy), insulation material (PBT vs. PCT), contact length dimensions, and operating temperature lower bound (-55°C vs. -40°C). Both parts share identical pitch, position count, mounting type, termination method, and compliance certifications.

Q: Are there any compatibility concerns with the insulation material change?

A: No. Both PBT and PCT insulation materials meet UL94 V-0 flammability requirements and provide equivalent environmental protection. The material change does not affect electrical performance or mechanical compatibility.

Q: Does the breakaway feature of the 3M part affect compatibility?

A: The breakaway feature is a design option that allows individual positions to be separated if needed. This does not affect compatibility with standard mating connectors or PCB layouts designed for the TSW-103-24-TM-S.

Q: What is the significance of the contact length difference?

A: The 929834-01-03-RK has approximately 0.030" shorter mating contact length (0.235" vs. 0.265"). This minor difference is within standard connector manufacturing tolerances and does not compromise mating depth or electrical contact reliability for standard 0.100" pitch applications.

Q: Are both parts RoHS compliant?

A: Yes. The TSW-103-24-TM-S is RoHS3 compliant, and the 929834-01-03-RK is RoHS compliant. Both meet current regulatory requirements for restricted substance elimination.
