Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF10-31S-2DSA(62) is determined by the following critical parameters:

Primary Matching Criteria:

• Connector type: Receptacle
• Contact type: Female socket
• Number of positions: 31
• Pitch - mating: 0.079" (2.00mm)
• Mounting type: Through hole
• Fastening type: Push-pull
• Contact finish - mating: Gold

Secondary Compatibility Parameters:

• Current rating: Minimum 2A
• Voltage rating: Minimum 250V
• Operating temperature range: Must encompass -30°C to 85°C
• Material flammability rating: UL94 V-0
• Insulation material: Polyamide (PA) or equivalent
• Contact material: Phosphor bronze or equivalent

Two substitute parts meet these criteria with varying degrees of parameter alignment and product status differences.

Engineering Selection Recommendations

DF10-31S-2DSA(72) (Hirose Electric Co Ltd)

This part is the primary substitute for the obsolete DF10-31S-2DSA(62). It maintains identical electrical and mechanical specifications across all critical parameters: 31 positions, 0.079" pitch, through-hole mounting, push-pull fastening, and gold-plated mating contacts. Both parts operate within the same temperature range (-30°C to 85°C) and carry identical current (2A) and voltage (250V) ratings. The DF10-31S-2DSA(72) is currently in active production status with 2474 units in stock, ensuring long-term availability. This part achieves ROHS3 compliance, providing regulatory advantage for new designs. The primary difference is termination method: the substitute uses solder termination versus the original's kinked pin configuration. This part is recommended as the direct replacement for the obsolete DF10-31S-2DSA(62).

831-41-031-10-001000 (Mill-Max Manufacturing Corp.)

This part provides an alternative substitute with enhanced electrical performance. It maintains the same 31-position, 0.079" pitch, through-hole, push-pull configuration with gold-plated mating contacts. The Mill-Max connector offers superior current rating (3A versus 2A) and extended operating temperature range (-55°C to 125°C versus -30°C to 85°C). However, this part differs in material composition: insulation uses polycyclohexylenedimethylene terephthalate (PCT) polyester instead of polyamide nylon, and contacts use beryllium copper instead of phosphor bronze. Contact length and insulation height show minor dimensional variations. The part is RoHS non-compliant and carries no specified voltage rating. This substitute is suitable for applications requiring higher current capacity and extended temperature performance, provided mechanical and material compatibility are verified for the specific application.

Frequently Asked Questions (FAQ)

Q: Can DF10-31S-2DSA(72) directly replace DF10-31S-2DSA(62) without PCB redesign?

A: The DF10-31S-2DSA(72) maintains identical pitch (0.079"), position count (31), mounting type (through-hole), and fastening mechanism (push-pull). Footprint compatibility is confirmed. The primary difference is termination method: kinked pin versus solder. PCB pad design must accommodate solder termination. Mechanical fit and electrical performance are equivalent.

Q: What are the key differences between the two Hirose substitutes?

A: DF10-31S-2DSA(62) uses kinked pin termination with 3.90µin gold plating on mating contacts. DF10-31S-2DSA(72) uses solder termination with 39.4µin gold plating. Both share identical electrical ratings (2A, 250V), temperature range (-30°C to 85°C), and mechanical dimensions. The DF10-31S-2DSA(72) is active production; the original is obsolete.

Q: When should the Mill-Max 831-41-031-10-001000 be selected over the Hirose DF10-31S-2DSA(72)?

A: Select the Mill-Max part when applications require higher current capacity (3A versus 2A) or extended operating temperature range (-55°C to 125°C versus -30°C to 85°C). Verify material compatibility: the Mill-Max uses beryllium copper contacts and PCT polyester insulation versus phosphor bronze and polyamide nylon in the Hirose part. Confirm mechanical fit due to minor dimensional variations in contact length (0.125" versus 0.110") and insulation height (0.165" versus 0.157").

Q: Are there compliance or regulatory differences between substitutes?

A: DF10-31S-2DSA(72) is ROHS3 compliant, supporting modern regulatory requirements. The Mill-Max 831-41-031-10-001000 is RoHS non-compliant. Both parts carry UL94 V-0 flammability rating and REACH unaffected status. For new designs subject to RoHS requirements, the Hirose DF10-31S-2DSA(72) is the appropriate selection.

Q: What is the inventory status for each substitute?

A: DF10-31S-2DSA(72) has 2474 units in stock. Mill-Max 831-41-031-10-001000 has 1070 units in stock. Both parts are available for immediate procurement.

Q: Can contact finish thickness variations affect connector performance?

A: Contact finish thickness differs across parts: DF10-31S-2DSA(62) has 3.90µin, DF10-31S-2DSA(72) has 39.4µin, and 831-41-031-10-001000 has 10.0µin on mating contacts. Thicker plating generally provides enhanced wear resistance and corrosion protection. All three parts meet UL94 V-0 flammability requirements. Verify finish thickness compatibility with application-specific environmental and cycling requirements.
