Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCF-112D1M,000 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Coil voltage: 12VDC
• Contact form: SPST-NO (1 Form A)
• Contact rating: 25 A minimum
• Switching voltage: 277VAC, 24VDC - Max
• Coil current: 75 mA
• Coil resistance: 160 Ohms
• Operating voltage thresholds: Must operate at 9 VDC, must release at 0.6 VDC

Mechanical Equivalence Requirements:

• Mounting type: Through Hole
• Termination style: PC Pin, Quick Connect - 0.250" (6.3mm)
• Operating temperature range: -30°C ~ 55°C
• Switching speed: Operate time 20 ms, release time 10 ms

Functional Equivalence:

• Relay type: General Purpose
• Coil type: Non Latching

Substitute parts must satisfy all electrical and mechanical parameters to ensure direct replacement capability without circuit redesign or board modification.

Engineering Selection Recommendations

PCF-112D2M,000 is the primary substitute for PCF-112D1M,000. Both parts are manufactured by TE Connectivity Potter & Brumfield Relays and share identical electrical and mechanical specifications. The PCF-112D2M,000 differs only in contact material composition (Silver Tin Oxide versus Silver Cadmium Oxide) and packaging format (Tray versus standard packaging). The PCF-112D2M,000 carries ROHS3 compliance and has significantly higher inventory availability (5043 units in stock). This part is classified as obsolete but remains functionally equivalent for direct replacement.

PCF-112D1M000 is a parametric equivalent with identical electrical and mechanical characteristics. This part is classified as active product status, making it the preferred long-term solution for new designs and ongoing procurement. The PCF-112D1M000 is available in Tube packaging with 750 units in stock. However, this part carries RoHS non-compliant status, which may present regulatory constraints depending on application requirements and regional compliance mandates.

Selection between PCF-112D2M,000 and PCF-112D1M000 should be based on compliance requirements and packaging preferences. For applications requiring RoHS compliance, PCF-112D2M,000 is the appropriate choice. For applications without RoHS constraints, PCF-112D1M000 offers active product status and extended availability.

Frequently Asked Questions (FAQ)

Q: Can PCF-112D2M,000 replace PCF-112D1M,000 directly on the circuit board?

A: Yes. The PCF-112D2M,000 is a direct substitute. Both parts share identical coil voltage (12VDC), contact form (SPST-NO), current rating (25A), mounting type (Through Hole), and termination style (PC Pin, Quick Connect - 0.250"). No circuit modifications or board redesign is required.

Q: What is the difference between PCF-112D2M,000 and PCF-112D1M000?

A: Both parts are electrically and mechanically equivalent to the original PCF-112D1M,000. The primary differences are: (1) PCF-112D1M000 is active product status while PCF-112D2M,000 is obsolete; (2) PCF-112D1M000 uses Silver Cadmium Oxide contact material while PCF-112D2M,000 uses Silver Tin Oxide; (3) PCF-112D1M000 carries RoHS non-compliant status while PCF-112D2M,000 is ROHS3 compliant; (4) packaging differs (Tube versus Tray).

Q: Which substitute part should be selected for new designs?

A: PCF-112D1M000 is the recommended choice for new designs due to active product status. However, compliance requirements must be evaluated. If RoHS compliance is mandatory, PCF-112D2M,000 is the appropriate selection despite obsolete status.

Q: Are there any performance differences between the contact materials used in these relays?

A: Contact material composition is specified in the provided parameters. PCF-112D1M,000 and PCF-112D1M000 use Silver Cadmium Oxide (AgCdO), while PCF-112D2M,000 uses Silver Tin Oxide (AgSnO). All three parts meet the specified switching voltage (277VAC, 24VDC - Max) and current rating (25A) requirements.

Q: What packaging options are available for these substitute parts?

A: PCF-112D1M,000 is supplied in standard packaging. PCF-112D2M,000 is supplied in Tray packaging. PCF-112D1M000 is supplied in Tube packaging. Packaging selection may impact procurement logistics and handling procedures.

Q: Can these relays be used in applications requiring RoHS compliance?

A: PCF-112D2M,000 is ROHS3 compliant and suitable for RoHS-regulated applications. PCF-112D1M,000 is RoHS compliant. PCF-112D1M000 is RoHS non-compliant and not suitable for applications with RoHS requirements.
