Grayhill 62S30-L4-P Rotary Encoder Optical 12PPR - Equivalent & Substitute Parts

Part Overview

The Grayhill 62S30-L4-P is an optical rotary encoder with 12 pulses per revolution (PPR) in quadrature (incremental) output configuration. This vertical-mounted encoder features a 1/4" diameter flatted end actuator, integrated detent mechanism, and built-in switch functionality. The component is designed for PCB through-hole mounting with PC pin termination and operates at 5V supply voltage.

The 62S30-L4-P maintains Active product status with full RoHS3 compliance and REACH unaffected classification. Identifying equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and maintain compatibility across production batches when the primary part number becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 62S30-L4-P are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Critical Parameters for Substitution:

• Encoder Type: Optical
• Output Type: Quadrature (Incremental)
• Pulses per Revolution: 12
• Voltage - Supply: 5V
• Actuator Type: 1/4" Dia Flatted End
• Detent: Yes
• Built-in Switch: Yes
• Mounting Type: PCB, Through Hole
• Orientation: Vertical
• Termination Style: PC Pin
• Rotational Life: 1M cycles minimum
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The Grayhill 62N30-P qualifies as a direct substitute because it matches all critical electrical and mechanical parameters. The primary difference is the series designation (62N versus 62S), which reflects a different product line within the Grayhill encoder portfolio while maintaining identical functional specifications and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 62S30-L4-P and 62N30-P are Active products manufactured by Grayhill Inc. with identical compliance certifications. Selection between these parts should be based on:

Availability and Supply Chain: The 62S30-L4-P currently maintains 1074 pieces in stock, while the 62N30-P has 755 pieces available. Either part can be selected based on inventory requirements and lead time considerations.

Compliance and Regulatory: Both parts carry ROHS3 compliance and REACH unaffected status, making them suitable for applications with equivalent regulatory requirements. The MSL rating of 1 (Unlimited) for both parts indicates no moisture sensitivity restrictions during storage or handling.

Functional Equivalence: The identical electrical specifications (5V supply, 12 PPR quadrature output) and mechanical characteristics (1/4" flatted end actuator, detent, built-in switch, vertical PCB through-hole mounting) ensure direct functional interchangeability in circuit designs.

Series Differentiation: The 62S and 62N series designations represent different product lines within the Grayhill encoder portfolio. Selection of either series does not impact electrical or mechanical performance for applications requiring the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the 62N30-P be used as a direct replacement for the 62S30-L4-P in existing designs?

A: Yes. The 62N30-P is a direct functional equivalent. All electrical parameters (5V supply, 12 PPR quadrature output), mechanical specifications (1/4" flatted end actuator, detent, built-in switch), mounting configuration (PCB through-hole, vertical orientation), and compliance certifications (ROHS3, REACH unaffected) are identical. No circuit modifications are required.

Q: Are there any differences in pin configuration or termination between these parts?

A: No. Both parts use PC pin termination style and are designed for PCB through-hole mounting. Pin configurations are identical.

Q: What is the significance of the series designation (62S versus 62N)?

A: The series designation indicates different product lines within the Grayhill encoder portfolio. However, for the specified parameters in this comparison, the series difference does not affect electrical performance, mechanical compatibility, or functional operation.

Q: Do both parts have the same rotational life specification?

A: Yes. Both the 62S30-L4-P and 62N30-P are rated for a minimum of 1 million rotational cycles, ensuring equivalent mechanical durability.

Q: Are there any moisture sensitivity or storage condition differences?

A: No. Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. Storage and handling conditions are equivalent.

Q: Which part should be selected based on current inventory?

A: Selection can be based on availability requirements. The 62S30-L4-P has 1074 pieces in stock, while the 62N30-P has 755 pieces available. Both are Active products with no supply discontinuation indicated.

Q: Are both parts suitable for RoHS3 and REACH-compliant applications?

A: Yes. Both the 62S30-L4-P and 62N30-P are ROHS3 compliant and REACH unaffected, making them suitable for applications with equivalent regulatory requirements.
