Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF13EA-10DP-1.25V(21) is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Hirose Electric Co Ltd
• Series: DF13
• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 10
• Number of Rows: 2
• Pitch - Mating: 0.049" (1.25mm)
• Row Spacing - Mating: 0.049" (1.25mm)
• Mounting Type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Current Rating: 1A
• Voltage Rating: 150V
• Operating Temperature: -35°C ~ 85°C
• Insulation Material: Polyamide (PA), Nylon
• Material Flammability Rating: UL94 V-0
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The DF13EA-10DP-1.25V(22) qualifies as a direct substitute based on full alignment with these parameters. The primary distinction between the main part and substitute is the fastening mechanism and product status, with the substitute featuring an active product status and detent lock fastening in place of push-pull fastening.

Parameter Comparison

Engineering Selection Recommendations

The DF13EA-10DP-1.25V(22) is the qualified substitute for the obsolete DF13EA-10DP-1.25V(21). Both parts maintain identical electrical and mechanical specifications across all critical parameters, including pitch, position count, current and voltage ratings, operating temperature range, and regulatory compliance.

The substitute part carries active product status with established supply availability (1329 pcs in stock versus 662 pcs for the obsolete variant), ensuring long-term procurement reliability. Both parts are RoHS compliant and carry identical UL94 V-0 flammability ratings, meeting the same regulatory and safety requirements.

The primary functional difference is the fastening mechanism: the substitute employs detent lock fastening in place of push-pull fastening. This change does not affect electrical performance or mechanical compatibility with mating connectors designed for the DF13 series. The substitute is supplied in Tape & Reel packaging, standard for production environments.

Frequently Asked Questions (FAQ)

Q: Are DF13EA-10DP-1.25V(21) and DF13EA-10DP-1.25V(22) electrically equivalent?

A: Yes. Both parts maintain identical electrical specifications: 1A current rating per contact, 150V voltage rating, -35°C to 85°C operating temperature range, and identical contact materials and finishes. Electrical performance is equivalent.

Q: What is the difference between push-pull and detent lock fastening?

A: Push-pull fastening uses a sliding mechanism for mating and unmating. Detent lock fastening uses a positive locking mechanism. Both are mechanical fastening methods that do not affect electrical connectivity or signal integrity.

Q: Can I use DF13EA-10DP-1.25V(22) as a direct replacement in existing designs?

A: Yes, provided the application does not require the specific push-pull fastening mechanism of the original part. The substitute maintains identical pitch, position count, mounting type, and electrical ratings. Mechanical compatibility with mating connectors designed for DF13 series headers is preserved.

Q: What is the significance of the packaging difference?

A: The substitute is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly and high-volume production. The original part packaging is not specified. Tape & Reel packaging is compatible with standard pick-and-place equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both DF13EA-10DP-1.25V(21) and DF13EA-10DP-1.25V(22) are RoHS compliant and carry UL94 V-0 flammability ratings, meeting identical regulatory requirements.

Q: Why is the original part obsolete?

A: The DF13EA-10DP-1.25V(21) is classified as obsolete by the manufacturer. The DF13EA-10DP-1.25V(22) is the active product variant within the same series and serves as the current production equivalent.
