Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCFN-112H2MG,000 are identified based on the following critical parameters that must align for functional compatibility:

Primary Matching Criteria:

• Coil voltage: 12VDC
• Contact form: SPST-NO (1 Form A)
• Mounting type: Through hole
• Termination style: PC pin
• Coil type: Non latching
• Contact material: Silver Tin Oxide (AgSnO)

Secondary Compatibility Factors:

• Contact rating current capacity
• Maximum switching voltage
• Operating temperature range
• Coil current and resistance
• Operate and release timing

Substitutes are grouped into two categories: parametric equivalents (identical electrical and mechanical specifications) and functional alternatives (compatible contact form and coil voltage with acceptable deviations in current rating or switching voltage).

Parameter Comparison

Engineering Selection Recommendations

PCFN-112H2MG000 (Parametric Equivalent)

This part is a parametric equivalent to the main part PCFN-112H2MG,000, offering identical electrical and mechanical specifications. The primary distinction is product status: PCFN-112H2MG000 is active and currently available, whereas the main part is obsolete. This substitute maintains all critical parameters including 26A contact rating, 277VAC maximum switching voltage, 96 Ohm coil resistance, and -25°C to 75°C operating temperature range. The packaging differs (tube versus unspecified for the main part). RoHS compliance status differs; PCFN-112H2MG000 is RoHS non-compliant while the main part is ROHS3 compliant. Selection of this substitute is appropriate for applications where RoHS non-compliance is acceptable and component availability is prioritized.

ALF1P12 (Functional Alternative)

The ALF1P12 from Panasonic Electric Works is a functional alternative suitable for applications where the contact rating and switching voltage requirements can accommodate reduced specifications. This substitute shares the same coil voltage (12VDC), contact form (SPST-NO), mounting type (through hole), and termination style (PC pin). The ALF1P12 operates at 20A contact rating and 250VAC maximum switching voltage, compared to 26A and 277VAC for the main part. The ALF1P12 features lower coil current (75 mA versus 125 mA) and higher coil resistance (160 Ohms versus 96 Ohms), resulting in reduced power consumption. Operating temperature range is -40°C to 60°C, narrower than the main part's -25°C to 75°C. The ALF1P12 is active and ROHS3 compliant. Selection of this substitute is appropriate for applications where the reduced current and voltage ratings are sufficient and lower coil power consumption is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the ALF1P12 directly replace the PCFN-112H2MG,000 in all applications?

A: The ALF1P12 is a functional alternative, not a direct replacement. It shares the same coil voltage, contact form, and mounting configuration. However, the ALF1P12 has a lower contact rating (20A versus 26A) and lower maximum switching voltage (250VAC versus 277VAC). Applications requiring the full 26A capacity or 277VAC switching capability must use the PCFN-112H2MG000 or equivalent. Applications with lower current and voltage requirements can use the ALF1P12.

Q: What is the difference between PCFN-112H2MG,000 and PCFN-112H2MG000?

A: These are the same relay with different part number formatting. PCFN-112H2MG,000 uses a comma separator, while PCFN-112H2MG000 uses no separator. The PCFN-112H2MG000 variant is currently active and available, whereas PCFN-112H2MG,000 is obsolete. All electrical and mechanical specifications are identical.

Q: Are there packaging differences between the substitute parts?

A: Yes. The main part PCFN-112H2MG,000 has unspecified packaging. The parametric equivalent PCFN-112H2MG000 is supplied in tube packaging. The functional alternative ALF1P12 is supplied in box packaging. Packaging selection may affect handling, storage, and integration into assembly processes.

Q: What are the RoHS compliance implications of these substitutes?

A: The main part PCFN-112H2MG,000 is ROHS3 compliant. The parametric equivalent PCFN-112H2MG000 is RoHS non-compliant. The functional alternative ALF1P12 is ROHS3 compliant. Applications subject to RoHS requirements should use either the main part or the ALF1P12. The PCFN-112H2MG000 is suitable only for applications where RoHS non-compliance is acceptable.

Q: How do the coil current specifications affect circuit design?

A: The main part and PCFN-112H2MG000 both draw 125 mA coil current at 12VDC, requiring 1.5W power dissipation. The ALF1P12 draws 75 mA coil current, requiring 0.9W power dissipation. Lower coil current in the ALF1P12 reduces power supply requirements and heat generation. Circuit designs must accommodate the specific coil current of the selected relay.

Q: What is the significance of the Must Operate Voltage specification?

A: The Must Operate Voltage indicates the minimum coil voltage at which the relay is guaranteed to energize. The main part and PCFN-112H2MG000 must operate at 7.8 VDC minimum. The ALF1P12 must operate at 8.4 VDC minimum. In low-voltage supply applications, the main part or PCFN-112H2MG000 provides better performance margin.

Q: Can the ALF1P12 be used in applications requiring 277VAC switching?

A: No. The ALF1P12 has a maximum switching voltage of 250VAC. Applications requiring 277VAC switching capability must use the PCFN-112H2MG,000 or PCFN-112H2MG000.

Q: What are the operating temperature considerations for each substitute?

A: The main part and PCFN-112H2MG000 operate from -25°C to 75°C. The ALF1P12 operates from -40°C to 60°C. The ALF1P12 provides lower temperature operation but does not reach the upper temperature limit of the main part. Applications in high-temperature environments above 60°C require the main part or PCFN-112H2MG000.
