SSW-103-02-S-P-RA Equivalent & Substitute Parts

Part Overview

The SSW-103-02-S-P-RA is a 3-position receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch spacing. This through-hole, right-angle connector features gold-plated mating contacts and tin-plated posts, rated for 4.7A per contact with an operating temperature range of -55°C to 125°C. The connector is constructed from liquid crystal polymer (LCP) insulation material and meets UL94 V-0 flammability standards. As an active product with ROHS3 compliance and MSL 1 rating, substitute parts may be required for design flexibility, inventory optimization, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSW-103-02-S-P-RA are qualified based on strict electrical and mechanical parameter matching within the SSW series. The substitution logic is determined by the following critical parameters:

• Connector Type & Position Count: All substitutes maintain receptacle configuration with 3 positions
• Pitch Specification: All substitutes maintain 0.100" (2.54mm) mating pitch
• Mounting Configuration: All substitutes maintain through-hole, right-angle mounting
• Contact Rating: All substitutes maintain 4.7A per contact current capacity
• Operating Temperature Range: All substitutes maintain -55°C to 125°C operating envelope
• Material & Compliance: All substitutes maintain LCP insulation, UL94 V-0 rating, and ROHS3 compliance
• Contact Finish: All substitutes maintain gold mating contact finish with tin post finish

The identified substitute parts (SSW-103-02-S-S-RA and SSW-103-02-SM-S-RA) are functionally equivalent within these parameters and may be used interchangeably in applications requiring the SSW-103-02-S-P-RA.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SSW-103-02-S-P-RA, SSW-103-02-S-S-RA, and SSW-103-02-SM-S-RA—are active products with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and product status. All parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. The MSL 1 rating for SSW-103-02-S-P-RA and SSW-103-02-SM-S-RA indicates unlimited moisture sensitivity protection, while SSW-103-02-S-S-RA carries MSL 1 with standard handling requirements. For applications requiring long-term storage or high-humidity environments, verify moisture sensitivity handling procedures with the selected part variant.

Frequently Asked Questions (FAQ)

Q: Can SSW-103-02-S-S-RA be used as a direct replacement for SSW-103-02-S-P-RA?

A: Yes. Both parts are 3-position receptacle connectors with identical pitch (0.100"), mounting type (through-hole right-angle), current rating (4.7A per contact), operating temperature range (-55°C to 125°C), and material specifications (LCP insulation, UL94 V-0). They are electrically and mechanically interchangeable.

Q: Can SSW-103-02-SM-S-RA be used as a direct replacement for SSW-103-02-S-P-RA?

A: Yes. SSW-103-02-SM-S-RA maintains all critical electrical and mechanical parameters identical to SSW-103-02-S-P-RA, including connector type, position count, pitch, mounting configuration, current rating, and operating temperature range.

Q: What are the key differences between these three part numbers?

A: The three parts are functionally equivalent. Differences exist only in internal design variants (indicated by the "S-P", "S-S", and "SM-S" designations) and moisture sensitivity level specifications. All maintain identical external electrical and mechanical performance characteristics.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three parts—SSW-103-02-S-P-RA, SSW-103-02-S-S-RA, and SSW-103-02-SM-S-RA—are ROHS3 compliant and REACH unaffected.

Q: What is the current rating for these connectors?

A: Each contact is rated for 4.7A. With 3 positions, the total connector current capacity is 14.1A when all contacts are fully loaded.

Q: What is the operating temperature range?

A: All three parts operate within -55°C to 125°C, suitable for industrial and commercial applications.

Q: Are these connectors suitable for high-reliability applications?

A: These connectors meet UL94 V-0 flammability standards and are constructed from liquid crystal polymer insulation with phosphor bronze contacts. Compliance certifications and material specifications support use in standard industrial applications within the specified operating parameters.
