Key Parameters

Substitute Part Grouping Explanation

Substitution of D-Sub 37 position receptacle connectors is determined by equivalence in core electrical and mechanical parameters: connector type (receptacle, female sockets), number of positions (37), shell size and layout (4, DC, C), mounting method (through hole), and termination style (solder). All listed substitute parts maintain these fundamental characteristics.

Secondary parameters that affect substitution compatibility include:

• Flange feature type (Mating Side Female Screwlock vs. Housing/Shell variants)
• Current and voltage ratings
• Operating temperature range
• Shell material finish (Nickel Plated vs. Tin or Tin-Nickel Plated)
• Contact material composition
• Dielectric material specification
• Regulatory compliance (RoHS, REACH status)

The following substitute parts are equivalent within the allowed mechanical and electrical parameter boundaries for this product category.

Parameter Comparison

Engineering Selection Recommendations

The L17HTNCHSOL2RM81C meets RoHS Compliance requirements and maintains Active product status with established manufacturing support. Selection of equivalent parts depends on application-specific electrical and environmental demands.

For applications requiring maximum electrical performance: The L17HTNCHSOL2RM81C (600V, 5A, -55°C ~ 150°C) and Amphenol ICC (FCI) Delta D series substitutes (D37S24A4GV00LF, D37S24A4GX00LF, D37S24A4PL00LF) provide higher voltage and expanded temperature operating ranges. The Delta D series components feature Phosphor Bronze contact material and are ROHS3 Compliant.

For applications with extended low-temperature requirements: The L17HTNCHSOL2RM81C operates to -55°C and accommodates the DC37S364TLF and Delta D series parts. The Assmann WSW A-DF 37 PP/Z limits operation to -20°C minimum and is not suitable for below-freezing environments.

For compliance-specific applications: ROHS3 Compliant options include A-DF 37 PP/Z and the Delta D series (D37S24A4GV00LF, D37S24A4GX00LF, D37S24A4PL00LF). REACH Affected status applies to Delta D series; REACH Unaffected status applies to A-DF 37 PP/Z, DC37S364TLF, and L17HTNCHSOL2RM81C.

For current-limited applications: The Assmann WSW A-DF 37 PP/Z is rated at 3A per contact, suitable only for applications with reduced current requirements below 3A.

Frequently Asked Questions (FAQ)

Q: Can the A-DF 37 PP/Z substitute for the L17HTNCHSOL2RM81C in all applications?

A: The A-DF 37 PP/Z is mechanically equivalent but has reduced electrical ratings (3A vs. 5A current, 250V vs. 600V voltage) and a narrower operating temperature range (-20°C ~ 105°C vs. -55°C ~ 150°C). Application requirements must be evaluated against these reduced specifications.

Q: What is the difference between Mating Side Female Screwlock and Housing/Shell flange features?

A: Mating Side Female Screwlock (4-40) features threaded connections on the receptacle flange. Housing/Shell variants feature either unthreaded or different threaded connector points (4-40 or M3). Mechanical mating interface compatibility must be verified against the corresponding plug connector specification.

Q: Are all substitute parts equivalent for PCB mounting?

A: All listed parts employ through-hole solder termination on standard D-Sub 37 position layout (4, DC, C). PCB footprint compatibility is maintained across all equivalents. Flange feature differences may affect mechanical mounting bracket compatibility.

Q: Why does the Delta D series (D37S24A4GV00LF, D37S24A4GX00LF, D37S24A4PL00LF) appear multiple times with different part numbers?

A: These parts represent the same Delta D series with variations in flange feature type. D37S24A4GV00LF features Mating Side Female Screwlock (4-40); D37S24A4GX00LF features Housing/Shell (4-40); D37S24A4PL00LF features Housing/Shell (M3). Selection depends on mechanical interface requirements.

Q: What impact do shell material finish differences have on selection?

A: L17HTNCHSOL2RM81C uses Nickel Plating; substitutes employ Tin or Tin-Nickel Plating. All finishes provide corrosion protection. Nickel plating offers superior performance in high-humidity and corrosive environments. Contact finish remains Gold (Flash) across all parts.

Q: Is the DC37S364TLF suitable for high-temperature applications?

A: The DC37S364TLF operates to 125°C maximum, lower than the L17HTNCHSOL2RM81C (150°C). For applications exceeding 125°C, only the L17HTNCHSOL2RM81C is suitable among listed parts.
