Substitute Part Grouping Explanation

Substitution of the DF20F-30DP-1H(59) is determined by strict equivalence across the following critical parameters:

• Connector Series & Type: Must remain DF20 series header with male pin contact type
• Position & Pitch Configuration: 30 positions at 0.039" (1.00mm) mating pitch with 2 rows at 0.039" (1.00mm) row spacing
• Mounting & Orientation: Surface mount, right-angle configuration with shrouded 4-wall design
• Electrical Ratings: 1A current capacity and 100V voltage rating
• Termination & Fastening: Solder termination with push-pull fastening mechanism
• Environmental Compliance: UL94 V-0 flammability rating, RoHS compliance, and MSL 1 rating

The DF20F-30DP-1H(52) meets all these criteria while offering active product status and improved availability. Differences in contact finish (gold vs. tin), insulation color, and packaging format do not affect functional interchangeability within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The DF20F-30DP-1H(52) is the direct functional equivalent for the obsolete DF20F-30DP-1H(59). Selection of the substitute part is justified by the following factors:

Product Status: The DF20F-30DP-1H(52) maintains active product status with Hirose Electric Co Ltd, ensuring continued manufacturing support and procurement availability. The original part is classified as obsolete, making the substitute necessary for new designs and ongoing production.

Compliance & Certification: Both parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification. The substitute achieves ROHS3 compliance, representing current regulatory alignment compared to the RoHS compliant original part.

Electrical & Mechanical Equivalence: All critical parameters—connector series, position count, pitch configuration, mounting type, shrouding design, termination method, and fastening mechanism—remain identical. Operating temperature range, voltage rating, and current capacity are functionally equivalent.

Contact Finish Difference: The substitute features gold contact finish compared to the original tin finish. Gold plating provides enhanced corrosion resistance and contact reliability, representing an improvement in performance characteristics without affecting mechanical or electrical interchangeability.

Packaging Consideration: The substitute is supplied in Tape & Reel format, standard for high-volume surface mount assembly operations, compared to bulk packaging of the original part.

Frequently Asked Questions (FAQ)

Q: Can DF20F-30DP-1H(52) be used as a direct replacement for DF20F-30DP-1H(59)?

A: Yes. Both parts are identical in connector series, position configuration, pitch spacing, mounting type, shrouding design, termination method, and fastening mechanism. The parts are mechanically and electrically interchangeable within all specified parameters.

Q: What is the significance of the contact finish difference between tin and gold?

A: Contact finish does not affect mechanical interchangeability. Gold plating provides superior corrosion resistance and contact reliability compared to tin. The substitute's gold finish represents an enhancement in performance characteristics.

Q: Does the packaging format change affect compatibility?

A: No. The packaging format difference (bulk vs. Tape & Reel) affects only procurement and assembly handling. The connector itself remains functionally identical. Tape & Reel packaging is standard for automated surface mount assembly.

Q: Are there any electrical parameter differences between the two parts?

A: No. Both parts maintain 1A current rating and 100V voltage rating. Operating temperature range (-35°C to 85°C) is identical. The substitute specifies 100VAC/DC, which encompasses the original 100V specification.

Q: Why is the original part classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and production decisions. The DF20F-30DP-1H(52) remains in active production, ensuring design continuity and supply chain stability.

Q: Are compliance certifications equivalent between the two parts?

A: Both parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification. The substitute achieves ROHS3 compliance, representing current regulatory standards compared to the original RoHS compliance designation.
