Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EM256506VR are identified based on strict electrical and mechanical parameter matching within the terminal block plug category. The primary substitution criteria are:

Critical Matching Parameters:

• Number of positions: 6
• Pitch spacing: 0.200" (5.08mm)
• Mounting type: Free Hanging (In-Line)
• Voltage rating: 300 V (UL)
• Screw termination with M3 fastener
• Tin contact mating finish
• UL94 V-0 flammability rating
• RoHS3 compliance

Allowable Variation Parameters:

• Current rating: Substitute parts rated 15 A are acceptable for applications not exceeding 15 A
• Wire gauge range: Substitute parts accepting 12-30 AWG accommodate the 12-26 AWG requirement
• Operating temperature: Substitute parts rated to 110°C exceed the 105°C requirement
• Contact material: Phosphor bronze substitutes for brass in equivalent electrical performance
• Housing material: Polyamide (PA66) substitutes for thermoplastic in equivalent mechanical performance
• Plug wire entry angle: 90° entry angle represents a distinct mechanical variant

Non-Substitutable Parameters:

• Plug wire entry angle (270° vs. 90°) determines physical installation orientation and cannot be interchanged without mechanical redesign

Parameter Comparison

Engineering Selection Recommendations

EM256506VR Primary Selection: Select the EM256506VR when 270° wire entry orientation is required and current demand does not exceed 16 A. This part maintains active production status with ROHS3 compliance and UL94 V-0 flammability certification. The 12-26 AWG wire gauge range accommodates standard industrial control wiring.

284041-6 Equivalent Substitute (270° Wire Entry): The TE Connectivity 284041-6 provides direct functional equivalence for applications requiring 270° wire entry configuration. This substitute accepts 15 A maximum current and supports expanded wire gauge range (12-30 AWG). The rising cage clamp termination mechanism and phosphor bronze contacts deliver equivalent electrical performance. Operating temperature rating extends to 110°C, exceeding the EM256506VR specification. Select 284041-6 when TE Connectivity supply chain preference exists or when expanded wire gauge compatibility is required, provided application current does not exceed 15 A.

284047-6 Mechanical Variant (90° Wire Entry): The TE Connectivity 284047-6 shares all electrical specifications with 284041-6 but features 90° wire entry orientation. This variant is not interchangeable with EM256506VR without mechanical redesign of the installation. Select 284047-6 only when 90° wire entry geometry is required by the application design.

Compliance and Certification: All three parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial control applications. Screw torque specifications are identical (0.79 Nm), ensuring consistent installation procedures.

Frequently Asked Questions (FAQ)

Q: Can 284041-6 directly replace EM256506VR in existing installations?

A: Yes, 284041-6 provides direct mechanical and electrical substitution for EM256506VR. Both parts feature 270° wire entry orientation, identical pitch spacing (5.08mm), M3 screw termination, and 300 V voltage rating. The 15 A current rating of 284041-6 is acceptable for applications not exceeding 15 A. Installation procedures and torque specifications remain identical.

Q: What is the difference between 284041-6 and 284047-6?

A: The primary difference is wire entry angle. 284041-6 features 270° wire entry (matching EM256506VR), while 284047-6 features 90° wire entry. All other electrical and mechanical specifications are identical. These variants are not interchangeable without physical redesign of the installation geometry.

Q: Can I use 284047-6 as a substitute for EM256506VR?

A: No. While 284047-6 shares identical electrical ratings and screw specifications, the 90° wire entry angle creates a distinct mechanical configuration. Substitution would require modification of the connector mounting and wire routing design. Use 284047-6 only when 90° wire entry geometry is specifically required.

Q: Are there wire gauge compatibility differences between these parts?

A: EM256506VR accepts 12-26 AWG wire. Both TE Connectivity substitutes (284041-6 and 284047-6) accept 12-30 AWG wire. The expanded range of the substitutes accommodates the EM256506VR requirement and provides additional flexibility for larger gauge conductors.

Q: What is the significance of the rising cage clamp termination in 284041-6 and 284047-6?

A: Rising cage clamp termination is a screw-based mechanism that provides secure wire retention. This mechanism is functionally equivalent to the standard screw termination of EM256506VR for electrical and mechanical performance. Both termination styles use identical M3 screw size and 0.79 Nm torque specification.

Q: Do operating temperature differences affect substitution decisions?

A: EM256506VR operates from -40°C to 105°C. Both TE Connectivity substitutes operate from -40°C to 110°C. The extended upper temperature rating of the substitutes exceeds the EM256506VR specification and does not create compatibility issues. Select based on actual application temperature requirements.

Q: Are contact material differences (brass vs. phosphor bronze) significant?

A: Both brass and phosphor bronze contacts with tin mating finish deliver equivalent electrical performance for this application category. Contact material selection does not affect substitution compatibility when voltage and current ratings are matched.

Q: What inventory considerations apply to these substitutes?

A: EM256506VR maintains 1044 units in stock. 284041-6 has 1949 units available, and 284047-6 has 1043 units available. All three parts maintain active production status with consistent supply availability.
