Substitute Part Grouping Explanation

Substitute parts for the QSS-025-01-F-D-A-K are identified based on electrical and mechanical parameter equivalence. The primary substitution criterion is packaging format. Both the main part and substitute maintain identical specifications across all critical parameters: connector type, number of positions, pitch, row configuration, mounting method, contact material and finish, board height, and compliance certifications.

The QSS-025-01-F-D-A-K is supplied in Tray packaging, while the substitute QSS-025-01-F-D-A-K-TR is supplied in Tape & Reel (TR) format. This packaging difference does not affect component functionality, electrical performance, or mechanical compatibility. Selection between these parts depends solely on assembly process requirements and inventory management practices.

Engineering Selection Recommendations

Both QSS-025-01-F-D-A-K and QSS-025-01-F-D-A-K-TR are active production parts with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts is determined by assembly process requirements:

Select QSS-025-01-F-D-A-K (Tray packaging) for manual assembly operations or low-volume production runs where tray-based component handling is preferred.

Select QSS-025-01-F-D-A-K-TR (Tape & Reel packaging) for automated pick-and-place assembly processes where tape-and-reel format is required for feeder compatibility.

Both parts satisfy identical functional requirements and are suitable for applications requiring 50-position surface mount connectors with 0.025" pitch and gold-plated center strip contacts.

Frequently Asked Questions (FAQ)

Q: Are QSS-025-01-F-D-A-K and QSS-025-01-F-D-A-K-TR electrically identical?

A: Yes. Both parts have identical electrical specifications including connector type, number of positions, pitch, contact material, contact finish, and finish thickness. They differ only in packaging format.

Q: What is the difference between Tray and Tape & Reel packaging?

A: Tray packaging is used for manual assembly and lower-volume applications. Tape & Reel packaging is designed for automated pick-and-place assembly equipment. The component itself is functionally identical in both formats.

Q: Can I substitute QSS-025-01-F-D-A-K-TR for QSS-025-01-F-D-A-K in my design?

A: Yes, provided your assembly process supports Tape & Reel format. The electrical and mechanical performance are identical. Verify that your pick-and-place equipment is compatible with the tape-and-reel format.

Q: Are both parts RoHS compliant?

A: Yes. Both QSS-025-01-F-D-A-K and QSS-025-01-F-D-A-K-TR are ROHS3 compliant.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Do these connectors require any special handling during assembly?

A: Both parts feature board guide and ground bus (plane) design with pick-and-place compatibility. Follow standard surface mount assembly procedures for 0.025" pitch connectors.
