The substitute parts listed below meet these criteria with documented electrical and mechanical compatibility within the specified parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

M20-7823242 (Harwin Inc.) This part is the primary substitute from the original manufacturer. It maintains identical electrical specifications (3A, 1000V) and operating temperature range (-40°C ~ 105°C). The only difference is the increased position count (32 vs. 31), which does not affect compatibility for applications using 31 positions. Active product status ensures ongoing availability and support. ROHS3 compliance is maintained.

801-43-031-10-001000 (Mill-Max Manufacturing Corp.) This part matches the exact position count (31) and pitch (0.100"). It provides enhanced current rating (4.5A vs. 3A) and extended operating temperature range (-55°C ~ 125°C). Voltage rating is not specified in the provided data. The connector type is receptacle with identical termination and fastening specifications. Active product status and ROHS3 compliance are confirmed.

PPPC311LFBN-RC (Sullins Connector Solutions) This header connector maintains 31 positions and 0.100" pitch with identical current rating (3A) and operating temperature range (-40°C ~ 105°C). The voltage rating is 250V, which is lower than the original 1000V specification. Contact finish is gold. This part is suitable for applications where voltage requirements do not exceed 250V. Active product status and ROHS3 compliance are confirmed.

PPTC311LFBN-RC (Sullins Connector Solutions) This header connector is functionally equivalent to PPPC311LFBN-RC with identical electrical and thermal specifications. The primary difference is tin plating on mating contacts instead of gold. Voltage rating remains 250V. This part is suitable for cost-sensitive applications where contact finish material does not impact performance. Active product status and ROHS3 compliance are confirmed.

Frequently Asked Questions (FAQ)

Q: Can M20-7823242 be used as a direct replacement for M20-7823142? A: Yes. M20-7823242 is the manufacturer-recommended substitute from Harwin Inc. It maintains identical electrical ratings (3A, 1000V), operating temperature range (-40°C ~ 105°C), and all critical mechanical parameters. The 32-position configuration is backward compatible for 31-position applications.

Q: What is the difference between receptacle and header connectors in this list? A: Receptacle connectors (M20-7823142, M20-7823242, 801-43-031-10-001000) accept mating plugs. Header connectors (PPPC311LFBN-RC, PPTC311LFBN-RC) are mounted on PCBs and accept receptacle connectors. Both types use identical pitch (0.100"), contact type (female socket), and termination (solder), making them mechanically compatible in board-to-board applications.

Q: Why do PPPC311LFBN-RC and PPTC311LFBN-RC have lower voltage ratings (250V vs. 1000V)? A: Voltage rating is determined by insulation material and design specifications. These Sullins connectors use polyester insulation, while the Harwin and Mill-Max parts use different materials. Applications requiring 1000V operation must use M20-7823242 or 801-43-031-10-001000.

Q: Is 801-43-031-10-001000 suitable for high-temperature applications? A: Yes. This Mill-Max part supports -55°C ~ 125°C, exceeding the original M20-7823142 range of -40°C ~ 105°C. It is suitable for extended temperature applications.

Q: What is the difference between PPPC311LFBN-RC and PPTC311LFBN-RC? A: Both parts are identical except for contact finish. PPPC311LFBN-RC has gold-plated mating contacts; PPTC311LFBN-RC has tin-plated mating contacts. Selection depends on application requirements for contact material and cost considerations.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (M20-7823242, 801-43-031-10-001000, PPPC311LFBN-RC, PPTC311LFBN-RC) are ROHS3 compliant, matching the original M20-7823142 specification.

Q: What packaging formats are available for these substitutes? A: M20-7823242 is supplied in tube packaging. 801-43-031-10-001000 is supplied in bulk. PPPC311LFBN-RC and PPTC311LFBN-RC are supplied in tray packaging. Packaging selection depends on procurement volume and handling requirements.
