TE Connectivity AMP Connectors 3-826631-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 3-826631-2 is an active rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This 32-position connector operates at 0.100" (2.54mm) pitch and is part of the AMPMODU Mod II series. The connector features male pins with gold-plated mating contacts and tin-plated posts, rated for 5A current and operating temperatures from -65°C to 105°C.

Substitute parts are identified when equivalent connectors share the same critical electrical and mechanical parameters, including pitch, position count, mounting style, termination method, and operating temperature range compatibility. Alternative sources ensure design flexibility and supply chain continuity for applications requiring this connector specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connectors is determined by strict alignment of electrical and mechanical parameters. The primary criteria for the 3-826631-2 include:

Critical Matching Parameters:

• Pitch specification: 0.100" (2.54mm)
• Position count: 32 positions
• Row configuration: Single row
• Contact gender: Male pins
• Mounting orientation: Through hole, right angle
• Termination method: Solder
• Fastening mechanism: Push-pull
• Shrouding configuration: Unshrouded
• Insulation material: Polybutylene Terephthalate (PBT)
• Flammability rating: UL94 V-0
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The Samtec Inc. TSW-132-08-T-S-RA meets all critical parameters and qualifies as a direct substitute. Both connectors share identical pitch, position count, row configuration, contact type, mounting style, termination method, and compliance certifications. Variations in contact length, insulation height, contact material composition, and contact finish specifications do not preclude substitution when the primary functional and electrical requirements align.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 3-826631-2 and Samtec TSW-132-08-T-S-RA are active products with ROHS3 compliance and UL94 V-0 flammability certification. Both connectors maintain MSL 1 moisture sensitivity classification and share identical ECCN and HTSUS codes, confirming regulatory and trade classification equivalence.

The TE Connectivity 3-826631-2 operates across an extended temperature range of -65°C to 105°C, while the Samtec TSW-132-08-T-S-RA operates from -55°C to 105°C. Applications requiring operation below -55°C must use the TE Connectivity part. For applications within the -55°C to 105°C range, both connectors are functionally equivalent.

Contact finish differences exist between the two parts: the TE Connectivity connector features gold-plated mating contacts with tin-plated posts, while the Samtec connector uses tin plating for both mating and post contacts. Contact material composition differs, with the TE Connectivity part using brass and the Samtec part using phosphor bronze. These material and finish variations do not affect substitution eligibility when electrical performance and mechanical compatibility are the primary design criteria.

Frequently Asked Questions (FAQ)

Q: Can the Samtec TSW-132-08-T-S-RA directly replace the TE Connectivity 3-826631-2 in all applications?

A: The Samtec TSW-132-08-T-S-RA is a direct substitute for applications operating within the -55°C to 105°C temperature range. Applications requiring operation below -55°C must use the TE Connectivity 3-826631-2, which supports -65°C minimum temperature.

Q: What are the key electrical and mechanical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching pitch (0.100" / 2.54mm), position count (32), row configuration (single row), contact type (male pins), mounting style (through hole, right angle), termination method (solder), fastening type (push-pull), shrouding (unshrouded), and insulation material (PBT). Both parts meet these criteria.

Q: Do the differences in contact finish affect connector performance?

A: Contact finish differences between gold-plated (TE Connectivity) and tin-plated (Samtec) mating surfaces do not affect substitution eligibility. Both finishes provide adequate electrical conductivity and corrosion resistance for standard applications. Contact material composition (brass versus phosphor bronze) similarly does not preclude substitution when electrical requirements are met.

Q: Are there differences in post length between these connectors?

A: Yes. The TE Connectivity 3-826631-2 has a post length of 0.126" (3.20mm), while the Samtec TSW-132-08-T-S-RA has a post length of 0.090" (2.29mm). Post length variations may affect PCB design and solder joint geometry. Verify PCB pad depth and solder joint requirements before substitution.

Q: Do both connectors meet the same compliance and regulatory standards?

A: Both connectors are ROHS3 compliant, UL94 V-0 rated, MSL 1 classified, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) codes. Regulatory and compliance equivalence is confirmed.

Q: What is the current rating for these connectors?

A: The TE Connectivity 3-826631-2 is rated for 5A current. Current rating information for the Samtec TSW-132-08-T-S-RA is not provided in the available specifications.

Q: Are both connectors available in equivalent packaging quantities?

A: The TE Connectivity 3-826631-2 is available in bulk packaging with 1124 pieces in stock. The Samtec TSW-132-08-T-S-RA is available in bulk packaging with 1104 pieces in stock. Both represent equivalent inventory availability.
