Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QTE-020-04-F-D-A-TR is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration (Header, Outer Shroud Contacts)
• Electrical interface: 40 positions, 2-row arrangement, 0.031" (0.80mm) pitch
• Mechanical compatibility: Surface mount, 0.600" (15.24mm) height above board, 16mm mated stacking height
• Contact material and finish: Gold plating at 3.00µin (0.076µm) thickness
• Functional features: Board guide and ground bus plane presence
• Compliance certifications: ROHS3 compliance and MSL 1 rating

The identified substitute differs only in packaging format (Tray versus Tape & Reel), which does not affect electrical or mechanical performance. All other specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the QTE-020-04-F-D-A-TR and QTE-020-04-F-D-A maintain Active product status with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than functional performance.

The QTE-020-04-F-D-A-TR in Tape & Reel packaging is suitable for high-volume automated assembly processes where continuous feed capability is required. The QTE-020-04-F-D-A in Tray packaging accommodates manual assembly operations or lower-volume production runs. Both parts satisfy ROHS3 compliance and MSL 1 moisture sensitivity requirements for standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can QTE-020-04-F-D-A be used as a direct replacement for QTE-020-04-F-D-A-TR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Tape & Reel versus Tray. Functional performance, connector interface, and board compatibility are unchanged.

Q: Does packaging format affect component performance or reliability?

A: No. Packaging format affects only handling, storage, and assembly process compatibility. Electrical and mechanical performance remain identical regardless of packaging.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical ROHS3 compliance certification and MSL 1 moisture sensitivity rating.

Q: Which packaging format should be selected for my application?

A: Selection depends on assembly process requirements. Tape & Reel (TR) is optimized for automated pick-and-place assembly. Tray packaging is suitable for manual assembly or lower-volume production environments.

Q: What is the pitch specification for this connector header?

A: The pitch is 0.031" (0.80mm), representing the center-to-center distance between adjacent contact positions in both rows.

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

A: Both parts meet ROHS3 compliance and carry MSL 1 rating, indicating suitability for standard industrial and commercial applications with unlimited moisture sensitivity tolerance.
