Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HL2-HTM-AC24V are selected based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Coil voltage: 24VAC
• Contact form: DPDT (2 Form C)
• Mounting type: Chassis Mount
• Coil type: Non Latching
• Contact material: Silver or Silver-based alloys

Secondary Compatibility Parameters:

• Contact rating current: 10A minimum (15A acceptable for higher capacity applications)
• Termination style: Quick Connect or Plug In compatible with 0.187" (4.7mm) standard
• Must operate and release voltage ranges within acceptable tolerance
• Operating temperature range overlap with application requirements

The substitute parts listed maintain electrical equivalence through matching coil voltage, contact configuration, and switching characteristics. Variations in coil current, operate/release times, and contact material composition are within acceptable engineering tolerances for general purpose relay applications.

Parameter Comparison

Engineering Selection Recommendations

LY2F-AC24 (Omron Automation and Safety): This direct manufacturer substitute maintains identical coil voltage, contact form, and current rating. The part is RoHS Compliant and carries active product status. Termination style differs (Plug In vs. Quick Connect), requiring mechanical interface verification. Operating temperature range is narrower (-25°C ~ 55°C) compared to the original part. Coil current is slightly lower at 46 mA. This substitute is suitable for applications within the specified temperature range where termination compatibility can be accommodated.

K10P-11AT1-24 (TE Connectivity Potter & Brumfield Relays): This substitute provides equivalent electrical performance with 10A contact rating matching the original specification. The part supports both Plug In and Quick Connect termination styles, offering mechanical flexibility. ROHS3 Compliant status and active product status ensure long-term availability. Operating temperature range extends to -45°C ~ 70°C, providing broader environmental coverage. Must release voltage is significantly lower at 2.4 VAC. This substitute is suitable for applications requiring quick connect termination compatibility.

K10P-11AT5-24 (TE Connectivity Potter & Brumfield Relays): This substitute provides higher contact rating at 15A, suitable for applications requiring increased current capacity beyond the original 10A specification. The part supports both Plug In and Quick Connect termination styles. ROHS3 Compliant and active product status ensure availability. Operating temperature range matches the original part at -45°C ~ 70°C. Contact material is Silver Cadmium Oxide (AgCdO), providing enhanced switching characteristics for certain load types. This substitute is appropriate for applications requiring higher current capacity or enhanced contact performance.

Frequently Asked Questions (FAQ)

Q: Can LY2F-AC24 be used as a direct replacement for HL2-HTM-AC24V?

A: LY2F-AC24 provides electrical equivalence in coil voltage, contact form, and current rating. However, termination style differs (Plug In vs. Quick Connect - 0.187"). Mechanical interface compatibility must be verified before substitution. Operating temperature range is narrower, limiting use in extreme cold environments below -25°C.

Q: What is the difference between K10P-11AT1-24 and K10P-11AT5-24?

A: Both parts share identical coil voltage, contact form, and termination options. The primary difference is contact rating: K10P-11AT1-24 is rated for 10A, while K10P-11AT5-24 is rated for 15A. Contact material also differs: K10P-11AT1-24 uses Silver (Ag), while K10P-11AT5-24 uses Silver Cadmium Oxide (AgCdO). Selection depends on required current capacity and load characteristics.

Q: Are all substitute parts compatible with quick connect termination?

A: LY2F-AC24 uses Plug In termination only. Both K10P-11AT1-24 and K10P-11AT5-24 support both Plug In and Quick Connect - 0.187" (4.7mm) termination styles, providing compatibility with the original part's quick connect interface.

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

A: HL2-HTM-AC24V operates from -50°C to 70°C. LY2F-AC24 operates from -25°C to 55°C, limiting use in cold environments. K10P-11AT1-24 and K10P-11AT5-24 both operate from -45°C to 70°C, providing broader coverage than LY2F-AC24 but not reaching the original part's lower temperature limit.

Q: How do coil current differences affect circuit design?

A: Coil current variations (46 mA to 52 mA) are within typical engineering tolerance for 24VAC relay applications. Circuit designs accommodating the original 50 mA specification will function with substitute parts. Coil resistance values (160-180 Ohms) remain consistent across substitutes, maintaining voltage drop characteristics.

Q: What compliance certifications apply to substitute parts?

A: LY2F-AC24 is RoHS Compliant. K10P-11AT1-24 and K10P-11AT5-24 are ROHS3 Compliant. All substitute parts carry EAR99 ECCN classification and HTSUS 8536.41.0050 tariff code, matching the original part's regulatory status.
