Part Overview

The SSQ-102-01-S-P is a 2-position rectangular receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated mating contacts, tin-plated posts, and is rated for -55°C to 125°C operation with 465VAC/655VDC voltage capability. The part is active in production and ROHS3 compliant. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part number becomes unavailable or when specific packaging or moisture sensitivity requirements differ.

Substitute Part Grouping Explanation

Substitute parts for the SSQ-102-01-S-P are qualified based on identical or equivalent electrical and mechanical parameters within the SSQ series. The substitution criteria are strictly limited to the following parameters:

Connector type (Receptacle)
Number of positions (2)
Pitch specification (0.100" / 2.54mm)
Mounting method (Through Hole)
Contact finish on mating surface (Gold, 30.0µin thickness)
Operating temperature range (-55°C ~ 125°C)
Voltage rating (465VAC, 655VDC)
Material flammability (UL94 V-0)
RoHS compliance (ROHS3)
Base product number (SSQ-102)

Variations in packaging type, moisture sensitivity level (MSL), and contact post finish do not disqualify parts from substitution, as these parameters do not affect electrical or mechanical compatibility in the connector interface.

Engineering Selection Recommendations

All four part numbers—SSQ-102-01-S-P, SSQ-102-01-SM-S, SSQ-102-01-S-S, and SSQ-102-21-S-S—are active production parts from Samtec Inc. and meet identical electrical and mechanical specifications for the SSQ series 2-position receptacle connector. All parts are ROHS3 compliant and rated for the same operating temperature and voltage parameters.

Selection between these parts should be based on:

Packaging requirements: SSQ-102-01-S-P, SSQ-102-01-S-S, and SSQ-102-21-S-S are supplied in bulk packaging; SSQ-102-01-SM-S packaging type is not specified in the provided data.
Moisture sensitivity level: SSQ-102-01-SM-S is rated MSL 1 (Unlimited); SSQ-102-01-S-P and SSQ-102-01-S-S are rated MSL Not Applicable; SSQ-102-21-S-S is rated MSL Not Applicable.
Current inventory availability: SSQ-102-01-SM-S (940 pcs), SSQ-102-21-S-S (854 pcs), SSQ-102-01-S-S (712 pcs), and SSQ-102-01-S-P (666 pcs).

Frequently Asked Questions (FAQ)

Q: Can SSQ-102-01-SM-S be used as a direct replacement for SSQ-102-01-S-P?

A: Yes. Both connectors share identical electrical and mechanical specifications, including 2-position configuration, 0.100" pitch, gold-plated mating contacts, through-hole mounting, and -55°C to 125°C operating range. The difference in moisture sensitivity level does not affect connector interface compatibility.

Q: What is the difference between SSQ-102-01-S-S and SSQ-102-21-S-S?

A: Both parts are electrically and mechanically equivalent. The difference in the part number suffix (01 versus 21) reflects a design or manufacturing variation within the SSQ-102 base product family, but all critical parameters for substitution are identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four part numbers—SSQ-102-01-S-P, SSQ-102-01-SM-S, SSQ-102-01-S-S, and SSQ-102-21-S-S—are ROHS3 compliant.

Q: Does packaging type affect electrical performance?

A: No. Packaging type (bulk versus other formats) does not affect the electrical or mechanical performance of the connector itself. Selection should be based on procurement and handling requirements.

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

A: Yes. All substitute parts are rated for continuous operation from -55°C to 125°C, supporting both industrial and high-temperature applications within this range.

Q: What voltage levels are these connectors rated for?

A: All parts are rated for 465VAC and 655VDC, suitable for standard industrial and commercial power distribution applications.
