Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QTH-090-03-L-D-A-TR is determined by equivalence across the following critical parameters:

• Connector type, position count, and pitch (0.020" / 0.50mm)
• Row configuration (2 rows)
• Surface mount mounting type
• Gold contact finish with 10.0µin thickness
• Board guide and ground bus features
• Height above board (0.404" / 10.27mm)
• Mated stacking height (11mm)
• RoHS3 compliance and MSL 1 rating

The identified substitute part QTH-090-03-L-D-A differs only in packaging format (Tray versus Tape & Reel). All electrical and mechanical specifications remain identical. This substitution is valid when packaging requirements permit tray format instead of tape and reel delivery.

Parameter Comparison

Engineering Selection Recommendations

Both the QTH-090-03-L-D-A-TR and QTH-090-03-L-D-A are active production parts with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts is determined by packaging requirements and inventory availability. The tape and reel format (TR) is suitable for automated assembly processes, while the tray format accommodates manual assembly or alternative handling methods. Both parts maintain full compliance with applicable regulations and certifications. The substitute part offers significantly higher inventory availability (92,700 pcs versus 774 pcs), which may influence procurement decisions when packaging format permits substitution.

Frequently Asked Questions (FAQ)

Q: Can QTH-090-03-L-D-A (Tray) be used as a direct replacement for QTH-090-03-L-D-A-TR (Tape & Reel)?

A: Yes, from an electrical and mechanical standpoint. Both parts are identical in all functional parameters. The difference is packaging format only. Substitution is valid if your assembly process can accommodate tray packaging instead of tape and reel delivery.

Q: Are there any performance differences between the tape and reel and tray versions?

A: No. Both versions have identical connector specifications, contact finish, pitch, position count, mounting type, and all other electrical and mechanical parameters.

Q: What determines whether these parts are substitutable?

A: Substitutability is based on matching the following parameters: connector type, position count (180), pitch (0.020" / 0.50mm), row configuration (2 rows), surface mount mounting, gold contact finish (10.0µin thickness), board guide and ground bus features, height above board (0.404" / 10.27mm), mated stacking height (11mm), RoHS3 compliance, and MSL 1 rating. Packaging format does not affect functional substitutability.

Q: Which part should I select if packaging format is not a constraint?

A: Selection should be based on inventory availability and procurement lead time. The QTH-090-03-L-D-A (Tray) has substantially higher stock levels and may offer faster delivery.

Q: Are both parts compliant with current regulations?

A: Yes. Both the QTH-090-03-L-D-A-TR and QTH-090-03-L-D-A are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity rating).
