CWN-551-26-0000 Equivalent & Substitute Parts

Part Overview

The CWN-551-26-0000 is a rectangular connector header manufactured by CW Industries, designed for through-hole mounting applications. This 26-position, 2-row connector with 0.100" (2.54mm) pitch serves board-to-cable/wire interconnection requirements. The part is currently active in production with 1021 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or when design requirements permit alternative contact geometries or fastening mechanisms.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-551-26-0000 is determined by strict alignment of the following parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 26
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

All three identified substitute parts meet these core criteria. Variations in contact shape (circular vs. square), contact finish materials (gold/nickel vs. gold/tin), fastening mechanisms (latch lock vs. push-pull), and insulation materials are permitted within the substitution scope, as these do not affect the fundamental electrical and mechanical interface compatibility at the mating surface.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and comply with ROHS3 or equivalent RoHS standards. The CWN-551-26-0000 and HARTING 09185266924 both support the full operating temperature range of -55°C to 125°C, while the 3M parts (N3429-6002RB and N3429-6003RB) are rated to -55°C to 105°C. Applications requiring operation above 105°C must use the CW Industries or HARTING alternatives.

The 3M parts provide higher current ratings (1.75A) compared to the CW Industries specification (1A), making them suitable for higher-current applications. The HARTING part does not specify a current rating but maintains compatibility with the core mating interface.

Contact post length varies across the substitute options: CWN-551-26-0000 at 0.090" (2.29mm), HARTING 09185266924 at 0.114" (2.90mm), N3429-6002RB at 0.112" (2.84mm), and N3429-6003RB at 0.155" (3.94mm). PCB design and through-hole depth must accommodate these variations during substitution.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 09185266924 be used as a direct replacement for the CWN-551-26-0000?

A: Yes. Both parts share identical mating pitch (0.100"), position count (26), row configuration (2 rows), row spacing (0.100"), shrouding (4-wall), and operating temperature range (-55°C to 125°C). Differences in contact shape (circular vs. square) and fastening mechanism (latch lock vs. push-pull) do not affect mating interface compatibility.

Q: What is the primary difference between the two 3M substitute parts?

A: N3429-6002RB and N3429-6003RB differ in contact post length: N3429-6002RB provides 0.112" (2.84mm) post length, while N3429-6003RB provides 0.155" (3.94mm) post length. Both maintain identical mating characteristics and electrical ratings. Selection depends on PCB through-hole depth requirements.

Q: Are there temperature limitations when substituting with 3M parts?

A: Yes. The 3M parts (N3429-6002RB and N3429-6003RB) are rated to -55°C to 105°C, compared to the CWN-551-26-0000 and HARTING 09185266924 rated to -55°C to 125°C. Applications requiring sustained operation above 105°C must use CW Industries or HARTING alternatives.

Q: Do all substitute parts meet the same RoHS compliance level?

A: The CWN-551-26-0000, HARTING 09185266924, and 3M N3429-6003RB are ROHS3 compliant. The 3M N3429-6002RB is RoHS compliant. Both compliance levels are acceptable for most applications; verify specific procurement requirements if ROHS3 certification is mandatory.

Q: What is the impact of different contact materials on substitution?

A: The CWN-551-26-0000 uses phosphor bronze contacts, while all substitute parts use copper alloy contacts. Both materials are suitable for the specified mating interface and do not prevent substitution. Contact finish (gold mating surface across all parts) ensures consistent electrical performance.
