Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCFN-112D2M,000 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Coil voltage: 12VDC (exact match required)
• Contact form: SPST-NO (1 Form A) (exact match required)
• Mounting type: Through hole (exact match required)
• Termination style: PC pin (exact match required)
• Switching voltage: 250VAC minimum (equal or higher acceptable)
• Contact material: Silver Tin Oxide (AgSnO) (exact match required)
• Coil type: Non-latching (exact match required)

Secondary Compatibility Criteria:

• Contact rating current: 20A minimum (higher ratings acceptable for load margin)
• Operating temperature range: Must encompass or exceed the original specification
• RoHS and REACH compliance status

The ALFG2PF12 from Panasonic Electric Works meets all primary and secondary compatibility criteria and qualifies as a direct substitute for the PCFN-112D2M,000.

Parameter Comparison

Engineering Selection Recommendations

The ALFG2PF12 is a qualified substitute for the PCFN-112D2M,000 based on the following factors:

Compliance and Regulatory Status: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards. The ALFG2PF12 carries additional approval agency certifications (cURus, VDE), providing enhanced qualification documentation.

Product Status Consideration: The PCFN-112D2M,000 is classified as obsolete, while the ALFG2PF12 maintains active product status. This distinction ensures long-term supply chain availability and continued manufacturer support for the substitute part.

Electrical Performance: The ALFG2PF12 provides a higher contact current rating (31A versus 20A), delivering additional load capacity margin. The operating temperature range of -40°C to 60°C exceeds the original specification of -30°C to 55°C, supporting broader environmental applications. Switching voltage, coil voltage, contact form, and timing characteristics remain identical.

Physical and Functional Compatibility: Both relays share identical mounting type (through hole), termination style (PC pin), contact material (Silver Tin Oxide), and coil operation (non-latching). These parameters ensure direct mechanical and electrical interchangeability in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the ALFG2PF12 be used as a direct replacement for the PCFN-112D2M,000 in existing designs?

A: Yes. The ALFG2PF12 meets all critical electrical and mechanical parameters required for direct substitution. Both relays operate at 12VDC, feature SPST-NO contact configuration, support 250VAC switching, and utilize identical through-hole PC pin termination. The higher current rating (31A) and extended temperature range of the substitute provide additional performance margin without compromising compatibility.

Q: What are the key differences between these two relays?

A: The primary differences are contact current rating (ALFG2PF12: 31A versus PCFN-112D2M,000: 20A), operating temperature range (ALFG2PF12: -40°C to 60°C versus PCFN-112D2M,000: -30°C to 55°C), product status (ALFG2PF12: active versus PCFN-112D2M,000: obsolete), and coil resistance (ALFG2PF12: 103 Ohms versus PCFN-112D2M,000: 160 Ohms). All other electrical and mechanical specifications remain equivalent.

Q: Does the difference in coil resistance affect circuit design?

A: The coil resistance difference (103 Ohms for ALFG2PF12 versus 160 Ohms for PCFN-112D2M,000) results in higher coil current for the substitute (117 mA versus 75 mA). Circuit designs must accommodate this increased current draw. The must-operate voltage (8.4VDC for ALFG2PF12 versus 9VDC for PCFN-112D2M,000) is lower, providing improved voltage margin in low-supply-voltage applications.

Q: Are there packaging differences between these parts?

A: Yes. The PCFN-112D2M,000 is supplied in tube packaging, while the ALFG2PF12 is supplied in bulk packaging. Procurement and inventory management processes may require adjustment to accommodate this packaging difference.

Q: What compliance certifications apply to the ALFG2PF12?

A: The ALFG2PF12 holds cURus and VDE approval agency certifications in addition to ROHS3 compliance and REACH unaffected status. These certifications provide expanded qualification documentation for safety and regulatory requirements in specific markets and applications.

Q: Is the ALFG2PF12 suitable for applications requiring the full -30°C to 55°C temperature range of the original part?

A: Yes. The ALFG2PF12 operating temperature range of -40°C to 60°C fully encompasses the original specification range of -30°C to 55°C, ensuring compatibility across all temperature conditions specified for the PCFN-112D2M,000.
