SS-132-T-18-N Equivalent & Substitute Parts

Part Overview

The SS-132-T-18-N is a 32-position receptacle connector from Samtec Inc.'s SS series, designed for board-to-board applications with 0.100" (2.54mm) pitch through-hole mounting. This active product features gold-plated mating contacts and tin-plated posts, with solder termination and push-pull fastening. The connector is constructed from glass-filled polybutylene terephthalate (PBT) insulation with beryllium copper contacts, rated for -55°C to 125°C operation. Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and sourcing options while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the SS-132-T-18-N are identified based on strict equivalence of the following critical parameters:

• Connector Type & Contact Type: Receptacle with female socket contacts
• Position Count & Pitch: 32 positions at 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Contact Materials & Finishes: Beryllium copper contacts with gold mating finish (30.0µin) and tin post finish
• Insulation Specifications: Glass-filled PBT insulation, black color, 0.100" height
• Operating Range: -55°C to 125°C
• Compliance: ROHS3 compliant, MSL 1

The substitute parts SS-132-T-18 and SS-132-T-29 maintain identical electrical and mechanical specifications across all critical parameters. Differences exist only in packaging configuration or internal design variants that do not affect functional compatibility in board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SS-132-T-18-N, SS-132-T-18, and SS-132-T-29—are active products from Samtec Inc. with identical electrical and mechanical specifications. Selection among these parts should be based on:

Product Availability: SS-132-T-18 and SS-132-T-29 maintain higher inventory levels (1102 and 1107 units respectively) compared to SS-132-T-18-N (864 units), providing sourcing flexibility for high-volume applications.

Compliance & Certification: All three parts meet ROHS3 compliance requirements and carry MSL 1 rating, suitable for unlimited moisture exposure without baking requirements.

Design Compatibility: Identical pitch, position count, contact geometry, and termination method ensure direct functional interchangeability in board-to-board connector applications without PCB redesign.

Temperature & Environmental Performance: All parts operate across the -55°C to 125°C range with equivalent contact materials and finishes, ensuring consistent performance in thermal cycling and corrosive environments.

Frequently Asked Questions (FAQ)

Q: Can SS-132-T-18 and SS-132-T-29 be used interchangeably with SS-132-T-18-N?

A: Yes. All three parts share identical electrical and mechanical parameters including connector type, position count, pitch, contact materials, finishes, insulation specifications, and operating temperature range. They are functionally equivalent for board-to-board applications.

Q: What determines substitutability for the SS-132-T-18-N?

A: Substitutability is determined by matching the following critical parameters: 32-position receptacle configuration, 0.100" (2.54mm) mating pitch, female socket contacts, through-hole solder termination, push-pull fastening, beryllium copper contacts with gold mating finish and tin post finish, glass-filled PBT insulation, and -55°C to 125°C operating range.

Q: Are there differences in contact reliability or lifespan between these parts?

A: No differences are specified in the provided parameters. All three parts use identical contact materials (beryllium copper), finishes (gold mating, tin post), and insulation materials (glass-filled PBT).

Q: Do all substitute parts meet the same compliance standards?

A: Yes. SS-132-T-18-N, SS-132-T-18, and SS-132-T-29 are all ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection without special handling requirements.

Q: What is the difference between SS-132-T-18-N and SS-132-T-18?

A: Based on provided parameters, both parts are functionally identical. The designation difference may reflect internal Samtec product line variants or packaging configurations that do not affect electrical or mechanical performance.

Q: Can these connectors be used in high-temperature applications?

A: Yes. All three parts are rated for -55°C to 125°C operation, suitable for industrial and automotive applications within this temperature range.

Q: Is there a preferred part number for new designs?

A: Selection should be based on inventory availability and supply chain requirements. All three parts are active products with equivalent specifications, making any suitable for new design implementations.
