Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF20F-20DP-1H(77) is determined by strict equivalence across the following critical parameters:

• Connector Series & Type: DF20 series header with male pin contacts
• Position Configuration: 20 positions in 2 rows
• Pitch Specifications: 0.039" (1.00mm) mating pitch and row spacing
• Mounting & Orientation: Surface mount, right-angle configuration
• Shrouding & Fastening: 4-wall shrouded construction with push-pull fastening
• Electrical & Environmental Ratings: 100VAC voltage rating, -35°C ~ 85°C operating temperature, UL94 V-0 flammability
• Compliance: RoHS compliant status and MSL 1 rating

The substitute part DF20F-20DP-1H(76) maintains identical electrical, mechanical, and environmental specifications. The primary distinction is packaging format: the original part uses standard packaging, while the substitute is supplied in Tape & Reel (TR) format. This packaging difference does not affect functional compatibility or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The DF20F-20DP-1H(76) is a direct functional equivalent to the obsolete DF20F-20DP-1H(77). Both parts are manufactured by Hirose Electric Co Ltd within the DF20 series and maintain identical electrical, mechanical, and environmental specifications. The substitute part carries Active product status, ensuring ongoing availability and manufacturing support.

Both parts meet RoHS compliance requirements and carry MSL 1 rating, indicating no moisture sensitivity constraints during storage and handling. The UL94 V-0 flammability rating is maintained across both variants, supporting applications with equivalent safety requirements.

The primary distinction is packaging format. The substitute part is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations. This packaging change does not affect component performance, electrical characteristics, or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can DF20F-20DP-1H(76) be used as a direct replacement for DF20F-20DP-1H(77)?

A: Yes. Both parts are electrically and mechanically identical. They share the same connector series, position count, pitch specifications, mounting configuration, and environmental ratings. The substitute part is the manufacturer-recommended equivalent.

Q: What is the difference between the two part numbers?

A: The primary difference is packaging format. The DF20F-20DP-1H(77) uses standard packaging, while the DF20F-20DP-1H(76) is supplied in Tape & Reel (TR) format. This distinction affects procurement and assembly logistics but not component functionality.

Q: Why is the original part marked as obsolete?

A: Product obsolescence typically reflects manufacturing discontinuation. The DF20F-20DP-1H(76) maintains Active status and serves as the current production equivalent, ensuring design continuity and component availability.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both parts maintain identical mating pitch (0.039" / 1.00mm), row spacing, shrouding configuration, and fastening mechanism. PCB footprints and mating connector interfaces are fully compatible.

Q: Do both parts meet the same compliance and certification standards?

A: Yes. Both parts are RoHS compliant, carry UL94 V-0 flammability rating, and maintain MSL 1 moisture sensitivity classification. Environmental operating range (-35°C ~ 85°C) and voltage rating (100VAC) are identical.

Q: What should be considered when transitioning from DF20F-20DP-1H(77) to DF20F-20DP-1H(76)?

A: Packaging format is the primary consideration. Tape & Reel format is optimized for automated assembly processes. If manual assembly or alternative handling methods are used, confirm that receiving and storage procedures accommodate TR packaging specifications.
