Mandatory Matching Parameters:

• Contact Form: SPDT (1 Form C)
• Coil Voltage: 6VDC
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Coil Type: Non Latching
• Operating Temperature Range: -40°C ~ 85°C
• Coil Resistance: 165 Ohms
• Must Operate Voltage: 4.1 VDC
• Must Release Voltage: 0.6 VDC

Allowable Variation Parameters:

• Contact Rating (Current): Equal or greater than 8A
• Coil Current: Within ±0.1 mA tolerance
• Seal Rating: Sealed configurations acceptable
• Coil Insulation: Class A or higher
• Contact Material: Varies by substitute
• Product Status: Active substitutes preferred for obsolete parts

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 3-1416200-8

The 3-1416200-8 is the direct functional equivalent of the 1416200-3. This part maintains identical electrical specifications including coil voltage, contact form, current rating, timing characteristics, and operating temperature range. The substitute is currently in active production status, ensuring long-term availability and supply chain continuity. The part is ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements. Packaging is provided in tube format. The coil current specification of 36.3 mA is within acceptable tolerance of the original 36.4 mA specification.

Secondary Substitute: 6-1416200-4

The 6-1416200-4 provides functional substitution with enhanced contact current rating of 10A compared to the original 8A specification. This part is also in active production status with ROHS3 compliance and REACH unaffected status. The coil insulation class is upgraded to Class F, providing superior thermal performance. The seal rating is specified as Sealed - Flux Protection rather than fully sealed. This substitute is suitable for applications where the higher current rating provides design margin. Packaging is provided in bulk format.

Both substitutes are manufactured by TE Connectivity and share the same base coil resistance, voltage thresholds, and timing characteristics as the original part. Selection between the two substitutes depends on packaging requirements and whether the enhanced current rating of the 6-1416200-4 is beneficial for the application.

Frequently Asked Questions (FAQ)

Q: Can the 3-1416200-8 be used as a direct replacement for the 1416200-3 in existing designs?

A: Yes. The 3-1416200-8 maintains identical electrical and mechanical specifications across all critical parameters including coil voltage, contact form, current rating, timing, and operating temperature range. The part is pin-compatible with through-hole PC pin termination and requires no circuit modifications.

Q: What is the difference between the two substitute parts?

A: The 3-1416200-8 is a direct specification match with 8A contact rating and Class A coil insulation. The 6-1416200-4 offers a higher 10A contact rating and Class F coil insulation with flux protection sealing. Both parts share identical coil voltage, timing, and operating characteristics. Selection depends on packaging preference and whether the higher current rating is required.

Q: Are both substitute parts currently available?

A: Yes. Both 3-1416200-8 and 6-1416200-4 are classified as active products with current inventory. The original 1416200-3 is obsolete, making these active substitutes necessary for continued production support.

Q: What is the packaging difference between the substitutes?

A: The 3-1416200-8 is supplied in tube packaging, while the 6-1416200-4 is supplied in bulk packaging. Packaging selection depends on production volume and handling requirements.

Q: Do the substitute parts meet current regulatory compliance standards?

A: Yes. Both 3-1416200-8 and 6-1416200-4 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Is the coil current difference between 36.4 mA and 36.3 mA significant?

A: No. The 0.1 mA difference between the original 1416200-3 (36.4 mA) and the 3-1416200-8 substitute (36.3 mA) is within normal manufacturing tolerance and does not affect circuit operation or performance.

Q: Can the 6-1416200-4 with 10A rating be used in place of the 8A rated original part?

A: Yes. The higher contact current rating of 10A is a superset of the original 8A specification. The 6-1416200-4 is electrically and mechanically compatible and provides additional current capacity margin for the application.

Q: What contact material is used in each substitute?

A: The 3-1416200-8 uses Silver Tin Oxide (AgSnO) contact material. The 6-1416200-4 uses Silver Nickel (AgNi) contact material. Both materials are suitable for general purpose relay applications at the specified voltage and current ratings.
