• Contact form: DPDT (2 Form C)
• Contact rating: 5 A
• Switching voltage: 115VAC, 28VDC - Max
• Coil current: 37.9 mA
• Coil type: Non Latching
• Coil resistance: 700 Ohms
• Must operate voltage: 13.5 VDC
• Must release voltage: 1.5 VDC
• Operate time: 4 ms
• Release time: 4 ms

Mechanical Parameters (Must Match):

• Mounting type: Through Hole
• Termination style: PC Pin
• Seal rating: Sealed - Hermetically
• Contact material: Silver Alloy

Environmental Parameters (Must Match):

• Operating temperature range: -65°C ~ 125°C
• Moisture sensitivity level: 1 (Unlimited)

The substitute part maintains identical performance characteristics across all specified parameters, ensuring functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the HFW5A1201K06 and HFW5A1130K00 are active production parts from TE Connectivity Aerospace, Defense and Marine. The parts are electrically and mechanically equivalent across all functional parameters.

Compliance Considerations:

The HFW5A1201K06 carries RoHS status as "Not applicable" with vendor-undefined REACH status. The HFW5A1130K00 is marked as RoHS non-compliant with REACH Unaffected status. Applications subject to RoHS or REACH regulatory requirements must account for these compliance differences when selecting between the two parts.

Packaging Consideration:

The HFW5A1201K06 packaging designation is not specified in available data. The HFW5A1130K00 is supplied in bulk packaging. Packaging selection depends on procurement quantity requirements and handling specifications for the application.

Inventory Status:

HFW5A1201K06: 713 units in stock HFW5A1130K00: 722 units in stock

Both parts maintain active inventory levels suitable for production applications.

Frequently Asked Questions (FAQ)

Q: Are the HFW5A1201K06 and HFW5A1130K00 electrically interchangeable?

A: Yes. Both relays share identical electrical specifications including coil voltage (26.5VDC), contact form (DPDT), current rating (5 A), switching voltage (115VAC, 28VDC - Max), coil current (37.9 mA), coil resistance (700 Ohms), and timing parameters (4 ms operate and release times). They function identically in circuit applications.

Q: What are the mechanical differences between these parts?

A: Both parts feature identical mechanical specifications: through-hole mounting, PC pin termination, hermetically sealed construction, and silver alloy contacts. No mechanical incompatibility exists between the two parts.

Q: Do these relays operate across the same temperature range?

A: Yes. Both the HFW5A1201K06 and HFW5A1130K00 operate across the identical temperature range of -65°C to 125°C.

Q: What is the significance of the different RoHS status between these parts?

A: The HFW5A1201K06 carries RoHS status as "Not applicable," while the HFW5A1130K00 is marked as "RoHS non-compliant." Applications subject to RoHS directives must select the appropriate part based on regulatory requirements. The HFW5A1201K06 may be the required choice for RoHS-regulated applications.

Q: How do the REACH compliance statuses differ?

A: The HFW5A1201K06 has vendor-undefined REACH status, while the HFW5A1130K00 is marked as REACH Unaffected. Applications requiring confirmed REACH compliance should clarify the HFW5A1201K06 status with the manufacturer or select the HFW5A1130K00 with defined REACH Unaffected status.

Q: What packaging options are available?

A: The HFW5A1130K00 is supplied in bulk packaging. The HFW5A1201K06 packaging specification is not defined in available documentation. Packaging requirements should be confirmed based on procurement and assembly process specifications.

Q: Can I substitute one part for the other in an existing design?

A: Functional substitution is supported based on identical electrical and mechanical parameters. However, compliance status differences (RoHS and REACH) must be evaluated against application regulatory requirements before substitution.

Q: What is the coil resistance of these relays?

A: Both relays have a coil resistance of 700 Ohms at 26.5VDC.

Q: What are the must-operate and must-release voltage thresholds?

A: Both relays must operate at 13.5 VDC minimum and must release at 1.5 VDC maximum, ensuring reliable switching performance across the specified voltage range.
