Key Parameters

Substitute Part Grouping Explanation

The SSQ-103-01-F-S qualifies as a direct substitute for the SSQ-103-21-F-S based on identical electrical and mechanical parameters. Both parts share the same base product number (SSQ-103), connector classification, contact configuration, and performance specifications. Substitution compatibility is determined by the following critical parameters:

• Connector type and contact type (Receptacle, Forked)
• Number of positions and pitch spacing (3 positions, 0.100")
• Mounting and termination method (Through Hole, Solder)
• Contact finish and material composition (Gold mating, Phosphor Bronze)
• Voltage and temperature ratings (465VAC/655VDC, -55°C to 125°C)
• Flammability and compliance certifications (UL94 V-0, ROHS3)

Parameter Comparison

Engineering Selection Recommendations

Both the SSQ-103-21-F-S and SSQ-103-01-F-S are active production parts with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on inventory availability and lead time requirements. The SSQ-103-21-F-S maintains higher stock levels (1,072 units), while the SSQ-103-01-F-S provides an alternative with 811 units available. Both parts meet UL94 V-0 flammability requirements and are suitable for applications requiring 465VAC or 655VDC operation across the -55°C to 125°C temperature range.

Frequently Asked Questions (FAQ)

Q: Are SSQ-103-21-F-S and SSQ-103-01-F-S electrically interchangeable?

A: Yes. Both parts share identical electrical ratings (465VAC, 655VDC), operating temperature range (-55°C to 125°C), and contact specifications. They are direct electrical equivalents.

Q: What are the mechanical differences between these parts?

A: There are no mechanical differences. Both connectors feature identical 3-position, 0.100" pitch receptacle configurations with through-hole solder termination, gold-plated mating contacts, and LCP insulation.

Q: Can I substitute SSQ-103-01-F-S for SSQ-103-21-F-S in existing designs?

A: Yes. The parts are mechanically and electrically identical, sharing the same base product number (SSQ-103) and all critical performance parameters. No design modifications are required.

Q: Are both parts RoHS compliant?

A: Yes. Both SSQ-103-21-F-S and SSQ-103-01-F-S are ROHS3 compliant.

Q: What is the difference in moisture sensitivity between these parts?

A: The SSQ-103-21-F-S lists MSL as Not Applicable, while the SSQ-103-01-F-S is rated MSL 1 (Unlimited). Both ratings indicate minimal moisture sensitivity for standard handling and storage conditions.
